Denver Broncos quarterback Mark Sanchez is worried that he missed out on a chance to secure a position as the team’s starting quarterback, he said after Saturday’s 31–24 loss to the San Francisco 49ers.

After starting the game by completing nine of 10 passes, Sanchez completed just one of his next eight. The veteran also fumbled the ball twice, including once in the red zone.

“I squandered a great opportunity to separate myself, and put the team in a bad situation,” Sanchez said, according to ESPN. “No excuse for that. Poor, poor quarterback play.

“I can’t put pressure on the O-line like that. I know I’m in a tough spot right there, and coach wants to see what I do. There’s no excuse for that. You can’t do that. ... Poor play. I just let one go tonight. That’s really too bad.”
